So pixel (60,40) would be index (40-1)*N+60 is there are N rows in your grid. </p> <p>The function `reorderSensorData' might be useful: it reorders the time series output from kspaceFirstOrder2D based on the angle that each sensor point makes with the centre of the grid.</p> <p>Ben </p> http://www.k-wave.org/forum/topic/what-row-in-the-sensor_datap-corresponds-to-pressure-field-at-what-node#post-4310 Sat, 15 Feb 2014 20:49:15 +0000 Gurashish singh 4310@http://www.k-wave.org/forum/ <p>How do you make out which row in the sensor_data.p corresponds to pressure field at which node in the mesh . Eg : If i want to know the pressure field at a point (60,40 ) on the grid , which row in the sensor_data.p would it correspond to . ? </p>
